How to Take a Good Measurement with a Laser Analyzer

Mikko Jarvikivi, Product Manager at Hitachi High-Tech Analytical Science, shares some tips on how to obtain the best measurement using the Vulcan handheld laser analyzer.

Cleaning the Vulcan

Although the measurement window of the Vulcan is well protected and recessed, it is important to clean the burn residue and dust from the measurement window every day, or more frequently if large amounts of samples are analyzed. The measurement window should be wiped clean with the supplied cotton buds by opening the nose lid with the provided tool. If the measurement window is not thoroughly cleaned even after using the cotton bud, then it should be wiped clean again with a new cotton dipped in pure “optical grade” (99.5%) isopropanol. Detergents or other alcohols should not be used to clean the window because this could leave a film on the window surface and affect the results. The camera window should also be cleaned with a cotton bud simultaneously.

Turning on the Vulcan

One must make sure that the battery is fully charged. It takes around 4–5 hours to charge the battery. About 8–10 hours of battery life can be obtained with typical usage. Taking measurements in a hot or cold environment might lead to a slight reduction in the battery life. The Vulcan handheld laser analyzer includes two batteries, which ensure that there are no interruptions in the work routine.

Turning on the Vulcan takes around 30 seconds. Once it is turned on, the user must wear the wrist strap to ensure extra protection. In order to access the Vulcan, a PIN code has to be entered. The default PIN code is “1111.” While operating a Class 3B laser, one must always remember to wear laser safety goggles. Each instrument comes with a pair of safety goggles.

Checking the Performance with Supplied Check Sample

A certified check sample is always provided for verifying the performance. It is always advisable to verify the performance daily. The check sample should be stored in a clean and dry environment, and surface dirt should be removed prior to a measurement.

The analyzer should be placed firmly against the sample such that it is in direct contact, thereby ensuring there is no gap between the analyzer and the sample. The measurement window as well as the proximity sensor window should be covered. When the instrument is ready to take a measurement, the red indicator light starts to flash.

The trigger has to be pulled and held until the ‘measurement complete’ sound is heard. The result is displayed on the screen. The grade ID and its chemistry have to be checked and compared with the certificate. Typically, the results should be within 5%–10% of the certified values.

Care should be taken to move the analyzer between measurements. The measurements should not be taken exactly from the same location.
